only cloud is what israel might do. absent an israeli attack is most likely iran gets nuclear weapons and very soon. >> greta: that description sort of suggests that americans looks feckless and week and may be no moment if they do go after a nuclear weapon and they see it's an economic hardship in the short run? >> i think they have concluded that despite president obama's rhetoric he is not really serious when he says all options are on the table. i think they have discerned the real administration policy despite its denials they think they can contain and deter a nuclear iran. i think that is delusional policy. in any event it doesn't stop with iran. saudi arabia, egypt and turkey get nuclear weapons as well but from iran's point of view they don't see united states as an obstacle. >> greta: is there any indication that the sanctions are working and i don't mean difficult for the iran people but working in terms of putting the brakes on their nuclear weapons program? >> no. there is no evidence it is put allege brake
